The U.S. Marshals Service said Kyle Levitt was taken into custody Saturday morning in Fairfax County, Va., where was living and working.
The Maricopa County Superior Court issued a warrant for his arrest Thursday following a year-long investigation by Tempe police.
Tempe police say 20-year-old Gabriel Batten died early in April 2012 after being shot at the Haven Luxury Apartments.
They say the victim and a small group of people were at the complex's pool about 2 a.m. when a fight broke out.
Police say Levitt pulled a gun and shot the victim in the abdomen.
It was unclear if the 26-year-old Levitt had an attorney.
